SNOW- PLOW.

SPECIFICATION forming part of Letters Patent No. 476,800, dated June 14,1892. Application filed December 24, 1891. Serial No. 416,074. (Nomodel.)

To all whom it may concern:

Be it known that I, JOSEPH KOLB, a citizen of the United States,residing at Belfast, in the county of Northampton and State ofPennsylvania, have invented a new and useful Snow-Plow, of which thefollowing is a specification.

The invention relates to improvements in snow-plows.

The object of the present invention is to simplify and improve theconstruction and to increase the strength and efliciency of snowplowswhich are coupled to and arranged in front of an engine.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a perspective view of a snow-plowconstructed in accordance with this invention. Fig. 2 is a rearelevation. Fig. 3 is a detail sectional view.

Like numerals of reference indicate correspondingparts in all thefigures of the draw lugs.

1 designates the frame of a snow-plow,\vl1icl1 is mounted 011truck-wheels 2 and which is adapted to be arranged in front of and to becoupled to an engine. The frame consists of triangular sides 3, whichtaper toward the front of the plow, and a sloping top 4, which istransversely curved and presents a convex surface. The top 4 has itsfront end 5 curved downward to bring the nose of the plow close to therails and to present an inclined surface to the snow. The bottom 6 ofthe frame is provided with a series of openings to receive thetruck-wheels, which are very small, to bring the frame of the plow aslow as possible and close to the rails. The truck-wheels 2 have theiraxles 7 journaled in suitable bearings, and the said wheels haveenlarged flanges 8 to prevent the plow jumping the rails.

On the top of the plow-frame is mounted a centrallongitudinally-disposed vertical blade 9, which has its front end 10enlarged to conform to the nose of the plow and which has connected toits rear end rearwardly-diverging wings 11. The wings are slightlyconcave and serve to throw the snow outward from the track and alsosupport the rear end of the longitudinal blade. The front end of thelongitudinal blade is supported and strengthened by a cross-bar 12,which has its end secured to the tops of vertically-disposed cutters 13,arranged at the sides of the plow and at the front thereof. The sidecutters 13 are substantially triangular and have their front and rearedges beveled. The wings are supported by a T-shaped brace 14, which ismounted on the back of the plow and is secured to and interposed betweenthe diverging wings.

The plow is provided at its rear end with a suitable car-coupler 15, bymeans of which it may be readily attached to a locomotive.

It will readily be seen that the snow-plow is simple, strong, anddurable, and is adapted to readily enter a snow bank or drift and clearthe track without seriously retarding the passage of a train.

WVhat I claim is* In a snow-plow, the combination of a frame comprisingtapering sides, a sloping top presenting a convex surface and having itsfront end inclined downward and a bottom provided with openings,truck-wheels arranged in said openings and supporting the frame, thelongitudinal blade, the wings diverging from the rear end of thelongitudinal blade, the side cutters arranged at the front of the frame,and the cross-bar secured to the cutters and theblade, substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.

JOSEPH KOLB.
